Re: [m2m-dev] FW: Quality Assessment of QVTO Model Transformations
|
Hello Ed Willink,
Thank you. Now I know that it is not easy to obtain a QVTo AST with full composition. You are right about my problem. The serialized AST I got seems to be the wrong one. Please find the QVTo file and the corresponding xmi file in the attachments
Is there any suggestion about obtaining a QVTo AST with full composition?
Best regards,
Phu

Hi Phu
If you have a true QVTo AST then it should compose/share all the
information you require.
When you invoke Resource.save to serialize, what is the URI in the XMI?
QVT 1.0 enabled at least three different interpreations of some AST
definitions and in some cases all three were wrong with the result that
not all child objects were composed and so those elements were omitted
from a serialized AST. Perhaps your problem is that you do not have a
QVTo AST with full composition.
Please post the XMI file resulting from Resource.save.
Regards

Hello,
First I would like to thank for
suggestions from Ed
Willink and Sergey.
I tried several ways and I have
found out that it is possible to obtain AST of corresponding QVTo file
by using the InternalTransformationExecutor:
InternalTransformationExecutor
executor = new InternalTransformationExecutor(transformationURI);
CompiledUnit
myCompiled = executor.getUnit();
OperationalTransformation
trans = executor.getTransformation();
Resource
res = trans.eResource();
EObject
qvtoModule = res.getContents().get(0);
Via the OperationalTransformation
object, generated AST can be accessed and it
certainly conforms to the metamodels QVTOperational.ecore
and ImperativeOCL.ecore
For
now it is possible to extract some information from the AST, i.e. names
of modeltype, transformation, name of mapping operations. However I
have not found out the way to access other parts, i.e. bodies of mapping
operation. Are there any suggestions?
Last
but not least, it would be much better to access the AST if there is a
way to serialize it. The ATL tool kit allows obtaining the file of ATL
model (generated AST) quite easily. I was wondering if QVTO tool kit
has a similar function?
If
you have any suggestions, please let me know. Thank you very much!
Best
regards,
Phu

Hi Phu,
QVTo engine is able to be launched outside Eclipse.
Inside Eclipse you can obtain AST of corresponding
.qvto by means of EMF Resource, i.e. some like follows:
URI uri = URI.createURI("file:/.../my.qvto");
Resource res = new ResourceSetImpl().createResource(uri);
EObject qvtoModule = res.getContents().get(0);
Generated AST is conformed to
org.eclipse.m2m.qvt.oml/model/QVTOperational.ecore (for QVTOperational
package) and
org.eclipse.m2m.qvt.oml.ecore.imperativeocl/ImperativeOCL.ecore (for
ImperativeOCL package). In fact that models have some (very minor)
deviations from official OMG QVTO metamodels.
Regards,
Sergey
